E40D slow TC lockup

[Oldred]

Update on this thread. Finally got some time this past weekend to tackle this trans. Changed fuid, filter, and solinod pack. It now shifts like a new transmission. I have driven it all week and so far so good. When I get some time I'll do some bench testing on the old solinod pack. Solinod pack was leaking at plug so it needed replacement anyway. I'm just curious if that was the culprit.

Oh yes. No problems. We will see how much further I can milk this transmission.
